Quantum systems cannot always be treated as isolated from their surroundings since this is an idealization which is not always true. Though theoretical analysis of open quantum systems poses great challenges as one needs ...

We study a free boundary problem arising from the modeling of an idealized electrostatically actuated MEMS device. In contrast to existing literature, we consider a three-dimensional device involving a hinged elastic plate. ...

In this thesis I present the results of photoassociation measurements in ensembles of
atomic calcium over an intensity range of below 1 W/cm2 up to 600 W/cm2. The temperature
of the atoms was reduced to 1 μK by laser and ...

The research examines the repositioning of peripheral villages in the framework of sustainable local development. For this, it evidences the current condition of villages facing complex challenges for their future. ...

Atom interferometers belong among today's most precise sensors and offer a broad range of possible metrological applications. Given their ability to measure accelerations and rotations precisely, they are suitable for ...

Especially for measurements in the UV spectral range the internal stray light is often a crucial contribution to the measurement uncertainty for array spectroradiometers. In this work a technical procedure for significant ...

Solar cells fabricated on multicrystalline silicon show a pronounced degradation of their energy conversion efficiency under illumination at elevated temperature. This effect is frequently denoted LeTID (’Light and elevated ...

The reaction-induced redistribution of vanadium oxide supported on noble metal
single crystal surfaces (inverse model catalysts), and the influence of surface acoustic waves (SAW) on the composition of a bimetallic Rh/Pt ...

The topic of this thesis is the initial link acquisition process for intersatellite laser interfer- ometers. Furthermore, a technique was studied that can be applied to enhance the signal to noise ratio of the established ...
